One US-based news outlet, USA Today has this account -

"A surgeon who had tested negative for the deadly Ebola virus in Sierra Leone before testing positive days later died Monday in Omaha, Nebraska Medical Center announced.

Martin Salia, whose family lives in Maryland, was flown to Omaha from Sierra Leone on Saturday and rushed to the medical center's specialized biocontainment unit.

"We are extremely sorry to announce that the third patient we've cared for with the Ebola virus, Dr. Martin Salia, has passed away as a result of the advanced symptoms of the disease," the hospital said on its Facebook page.

"It is with an extremely heavy heart that we share this news," Phil Smith, medical director of the Biocontainment Unit at the hospital said in the statement. "Dr. Salia was extremely critical when he arrived here, and unfortunately, despite our best efforts, we weren't able to save him."

Tim Shenk, spokesman for Doctors Without Borders, said "false negative" test results are possible in the first days of symptoms when the viral load is relatively low. Salia was retested Nov. 10; that test was positive.

Smith said Salia was suffering from advanced symptoms of Ebola when he arrived in Nebraska, including kidney and respiratory failure. He was placed on dialysis, required a ventilator and received plasma, Smith said. Multiple medications included experimental ZMapp therapy, a new drug that has shown promise in fighting the disease."

On the Facebook page of the hospital we found this -

"Dr. Salia arrived at the Biocontainment Unit on day 13 of his disease. (Other Ebola patients got here on days 6 and 8.) Dr. Salia was unresponsive, had no kidney function and was working hard to breathe. He went into cardiac arrest Monday morning and passed away around 4:00 a.m.

"We gave it everything we could," said Dr. Johnson, Division Chief of Critical Care Anesthesiology. "Our staff worked around the clock to save him. He was given a dose of convalescent plasma and ZMapp therapy.

We also tried dialysis and respiratory support." Our staff is deeply saddened and grieving this loss, but they are still dedicated to treating Ebola patients. "I want to thank our local heroes who took care of a global hero," said Morris.

"Their work was second to none."

The death of Dr Martin Salia once more throws into the spotlight questions about how the first outward signs of infection are treated.

Are we getting it right? Are we too slow in reacting quite forgetting that once the Ebola beast of a virus gets into the human system, it gets to work immediately, multiplying and attacking all the body's defensive system?

The unit that took up Dr Salia's case says that he arrived on day 13 of his disease and that other Ebola patients they treated got to the hospital on days 6 and 8 meaning that the time gap - those vital days, hours, minutes and seconds are quite important - that they should not be lost. And this again buttresses our fears that we are leaving things too late for any intervention to work for the good of the afflicted. This is where delay costs lives.

We have now lost six doctors and in this latest case of Dr Martin Salia we hear of initial tests that proved negative only for a further test some days later to prove that he was indeed positive for the virus.

Is there something wrong with the testing lab or should there be a more robust testing sequence that should deliver results within hours - even then too long a period for such a vicious and malevolent beast.

Even as we mourn the passing away of another fallen hero in the fight against the Ebola scourge, let us not lose hope. Let us learn from our mistakes to save more lives as indeed latest figures from Sierra Leone show that we do not only have more unreported deaths, but that those in charge of the Sierra Leone sector in the fight against the virus have still not got their priorities right.

We offer our condolences to the bereaved immediate family - partner Isatu, the children and the wider family members. May the Good Lord in His mercy, grant Dr Martin Salia the peace that only He can give.

AMEN

Rest In Peace
